RAZOR STROPIER.

Application filed January 10, 1922.

To all whom t may concern.'

Be it known thatJ I, EDWARD B. GIFoRD,

a citizen of the United States, and residing at Adrian, in the county ofLenawee and 6 State of Michigan, have invented a new and Improved RazorStropper, of which the following is a specification.

This invention relates to means for stropping razor blades, and itsobject is to provide a simple and efficient stropping mechanism whichcan be made at low cost and which can be folded so as to occupy aminimum of space.

In the accompanying drawing, Fig. 1 is a plan of this stropper with astrop and razor blade in operative position. Fig. 2 is a side elevationthereof. Fig. 3 is a. section on the line 3-3 of Fig. 1. Fig. l is asection on the line 4-41 of Fig. 3. Fig. 5 is a bottom plan of amodified forni of this stropper.

Similar reference characters refer to like parts throughout the severalviews.

A channel-like base 1 has curved edges 2 adapted to slide along thebottom side of the strop 3 and has end ears 4 bent up parallel to eachother and at right angles to the strop. These ears are perforated toreceive the shafts 5 and 6, a roller 7 being mounted 39 on the shaft 6which is so positioned that the axis of the roller 7 is parallel to thetop of the strop and the roller depresses it between the edges 2 thuscausing greatly increased friction between the roller and strop.

A blade holder 8 having the resilient jaws 9, is secured to the shaft 5and the two shafts are connected by the gears 10 and 11. A stirrup 12 ismounted on the pivot 13 secured to the base 1, and its ears 14 haveholes 15 to receive the small lateral trunnions 16 on the handle 17.This stirrup 12, the pivot 13 and the trunnions 16 constitute a swivelbetween the handle 17 and the base 1. The handle has a curved end 18 andside flanges 19 to position the first finger and thumb of the hand whichmoves the blade back and forth along the strop, as indicated by thedotted lines of Fig. 2.

Any desired type of blade 20 may be inserted between the jaws and theblade will be swung around on the axis of the shaft 5 each time themovement is reversed. The swivel connection between the base and the thestrop without binding. The curved Serial No. 528,218.

edges 2 of the base cause very little friction so that the razor may bemoved back and forth along the strop with a minimum eX- penditure ofwork. The jaws 9 which engage the razor blade may be given any formnecessary to properly grip substantially every type of blade or theholder in which it is mounted.

In Figs. 1 to 4 the stropper is shown with the pivot 13 equal distancesfrom the side ears 4.. Then thus positioned the pull of the handle 17conveyed to the base l by the pivot 13 causes the roller 7 and theshafts 5 and 6 to remain at substantially right angles to the edges ofthe strop 3. Many men, however, prefer to draw the blade 20 along thestrop with the edge of the blade at an oblique angle to the edges of thestrop, as indicated in dotted lines. This is accomplished by positioningthe pivot 13 at one side of the middle of the base 1, as indicated inFig. The pull of the handle 17 now causes the short end of the base toalways be in advance of the other end and the blade 2() to liediagonally of the strop. Upon the reverse movement of the handle thebase also changes its position so that the lines of stropping onopposite sides of the blades will cross.

The details and proportions of the several parts may all be changed bythose skilled in the art without departing from the spirit of myinvention as set forth in the following claims.

1. In a razor stropping device, the combination of a channel shaped basehaving rounded edges and upwardly extending perforated ears, a pair ofshafts mounted in said ears and gears connecting the shafts, a roller onone shaft to depress the strop below the plane of the edges of the base,a razor blade holder mounted on the other shaft, and a handle connectedto said base roller on one shaft to depress the strop below the plane ofthe edges of the base, :i razor blade holder mounted on the other shaft,e flat handle, a universal joint coinprising n pin Connected to the basebetween its edges and et one side of the middle there of, and :i stirruppivotelly mounted on said pin, seid handle beiner pivoted to saidstirrup on :i line at right angles to the axis of seid pin.

3. In a razor stropping device, the combination of a channel shaped basehaving rounded edges and upwardly extending perforated ears, uper of'sbatte mounted in seid ears and gears connecting the shafts, 1t rolleron one shelt to depress the strop be low the plane of the edges ot' thebuse, :i rzizor blade holder mounted on the other shaft, end e handleconnected by e universal joint to said base between said eure und at oneeide oil the middle ol the heee so :is to 'anse the base und bladeholder to be at oblique :ingles to the edges of the strop :1s thestropper is moved beek and forth along;` the strop.
